6 Claims.

This invention relates to wall insulation and particularly insulation for occupying the spaces between the upright studs of a wall.

An object is to employ a highly effective combination of fibrous packing material with cellular sheets of fiber board for wall insulating purposes.

Another object is to pack fibrous insulation within a wall against a horizontally corrugated face of a cellular sheet or sheets, so that this corrugations oifer a considerable resistance to settling of the fibrous packing.

A further object is to employ cellular wall board to form a chamber within a wall to receive a fibrous insulating packing and to form dead air spaces at the inner and outer sides of such chamber. I

A further object is to so arrange inner and outer sheets of cellular fiber board within a wall as to form a chamber between such sheets and also form dead air spaces between the sheets and inner and outer coverings of the wall.

These and various other objects are attained by the construction hereinafter described and illustrated in the accompanying drawings, wherein:

Fig. 1 is a fragmentary interior elevational View of a wall to which the improved insulation is applied, omitting lath and plaster, and breaking away certain portions.

Fig. 2 is a cross sectional view of the same, taken on the line 2- -2 .of Fig. 1.

Fig. 3 is a vertical sectional view of the same taken on the line 33 of Fig. 2.

Fig. 4 is a perspective view of one of the auxiliary fiber board sheets employed.

Fig. 5 is a perspective view of one of the main fiber board sheets.

Fig. 6 is a perspective view of a fiber board sheet serving to form a horizontal partition within the wall.

Fig. '7 is a perspective view of a fiber board spacer element.

In these views, the reference characters I, 2, and 3 designate upright studs incorporated in a wall, the studs I and 2 being represented as occupying a standardized spaced relation and the studs 2 and 3 having such a lesser spacing as is frequently necessary. To the inner faces of bottom of each sheet 8 is similarly inwardly flanged as indicated at I8, and tongues I I formed at the junctures of the flanges 9 and I8 are upwardly bent to lie against the flanges 9. The upper marginal portion of each sheet 8 is flanged outwardly, as indicated at I2 to bear against the sheathing 6 and the ends of such portion are upwardly bent to form tongues I3 bearing against the studs I and 2. The sheets 8 are secured to the studs at suitable points by brads I4, certain of which serve also to holdthe tongues II and I3 in their described positions. At the junctures of the sheets 8, both the flanges 9 and main bodies of the sheets snugly engage each other;

To assure a desired spacing of the sheets 8 from the sheathing 6, it is preferred to tack or otherwise secure spacing strips E5 to the sheathing in centrally opposed relation to said sheets, said strips being scored and bent to form vertically elongated, V-shaped projections I6 which form seats for the sheets 8.

The flanges 9 and II! are set back from the inner faces of the studs I and 2, and seating against such flanges between the inner portions of said studs is a horizontally corrugated sheet I! of fiber board, scored and bent along its lateral'and bottom margins to form vertical flanges I8 and a horizontal flange it which project inwardly to a substantially flush relation with the inner faces of the studs so as to engage or at least closely approach the inner covering 4, 5, when applied. Tongues 20, which are formed at the junotures of the vertical and horizontal flanges I1 and I9 are preferably upwardly bent to bear against the vertical flanges.

It is of importance that the sheets 8 and I! are both formed of single-faced corrugated board, and that the 'unfaced horizontally corrugated faces of said sheets are arranged to define the sides of chambers formed between said sheets 8 and I1.

The chamber between the sheets 8 and I! are filled with a packing of light material of heat insulating character and productive of numerous dead air interstices, such "as the matted mineral wool indicated at 2 9. Engagement of this filling by the horizontal corrugations of the sheets 8, the flanges 9 of such-sheets, and the sheets I! offer a considerable resistance to settling of said packing. Further resistance to such settling may be created by driving nails 22 partially into the studs I and 2 at suitable points, such nails extending from the studs some distance into the packing 2|.

In case it is desired to render the height of the chambers which receive the insulating mass 2| less than the length of the sheets 8, partitioning strips 23 of corrugated, fiber board may be inserted, one thereof being shown, such strip being equal in width to the flanges 9 and I8 and having upwardly bent end portions 24 which lie against the flanges 9, and are tacked or otherwise secured to the studs through said flanges. It will be noted that the strip 23 inclines upwardly at approximately forty-five degrees as it extend from the sheet 8, its resistance to sagging under load of the superposed packing 2| being thus materially increased. The end portions 24 are of a triangular form (see Fig. 6) so that they have edges which may bear vertically against the sheet 8, in establishing the inclined position of the strip.

Between studs such at 2 and 3 which are spaced apart considerably less than the standard distance, there are inserted, in end-to-end relation, vertically elongated, horizontally corrugated, single-faced, substantially U-shaped sheets 25, the connecting portions 25 of which are approximately V-shaped and disposed against the sheathing 6, so as to form dead air spaces in proximity to the sheathing. Said sheets terminate short of the inner faces of the studs, similarly to the flanges 9 and I and vertically elongated strips 21 of horizontally corrugated, singlefaced board are fitted between the inner ends of the studs 2 and 3, seating against the sheets 25, such strips being scored lengthwise and marginally bent to form opposed flanges 28 projecting to and terminating substantailly flush with the inner faces of said studs. The sheets and strips 2'! form a chamber receiving a packing 2| of insulating material, as previously described,

and the corrugated faces of said sheets and strips strongly resist settling of such packing,

Preferably all of the described corrugated sheets or elements will be treated with creosote or some other suitable chemical to materially increase their resistance to moisture.

The described construction, by combining the heat insulating properties of cellular fiber board and a fibrous mass of packing, very effectively resists the transmission of heat through a wall. The materials are inexpensive and the construction is such as to permit quite rapid installation of the insulation.

The use of mineral wool and similar loose fibrous packings has occasionally been criticized on the grounds that moisture will deposit on such packing and be retained thereby in case air withtion in maintaining the lower ends of the sheets 8 a proper distance from the sheathing.

The invention is presented as including all such modifications and changes as come within the scope of the following claims.

What I claim is:

1. In a wall insulation, the combination with spaced upright studs and inner and outer coverings for the studs, a fiber board spacer element secured to one of the coverings between the studs and elongated approximately vertically and bent to form an air passage within and extend- Lil ing the full length of the element, a sheet of cellular fiber board extending between the studs and engaging said spacer element, fastening means connecting said sheet to each of the studs, and a packing of loose insulating material between said studs and held by said sheet in a desired spaced relation to the covering carrying said spacer.

2. In a wall insulation, the combination with spaced upright studs and inner and outer coverings for the studs, a sheet of cellular fiber board extending between the studs in spaced relation to one of said coverings, a cellular fiber board spacer element interposed between the last mentioned covering and said sheet, and fixedly secured to one thereof, and spaced from the studs,
